Yes. Because, the incentives for companies are too big to ignore. The math being done right now is $10/hr for voice support in (say) the Phillipines is much more than $0.10/hr having an AI do it, even factoring in the cost of some customer churn. And the risk of the latter for some services can be discounted to zero if the user has no viable alternative.

Second, the best support line is one where no one calls in. So there are strong incentives to make it hard to do so, either positive (create good self service options) or bad (hide the number, hide emails, etc).

If you don't want this future then make sure you always ask for the human and constructively provide feedback that you will penalize any supplier that relies on it.

We are already in a K shaped economy wrt call centers. Being a very frequent Hilton hotel guest, say, gets you a separate call center number, US based live human support, people who can solve your problem, etc. Not being a Hilton member gets you the 45 minute wait and a bot.
